I've used this for a few months, but the usage was minimal as I primarily breastfed. However, there is some discoloration due to long-term home storage (see photo 5), but it doesn't affect its use. Comes with the original box (the box is not in great condition). Includes the instruction manual. Also includes a Pigeon baby bottle (see photo 6). Please purchase only if you understand that this is a used item. Product description below. A custard-colored sterilizer that can be easily sterilized in the microwave. - Brand: Combi - Product Name: Jokin Sho-zu α - Type: Microwave Sterilizer - Color: Custard - Features: Design with ventilation holes Thank you for looking.
